3d4ef74c9b Encode the ifaces a class implements in metadata 
This lets you use class A as if it had type B if A implements B,
and A and B are in different crates from your own.

Closes #2285

164039e867 Don't re-export a glob-imported ID when the same ID is defined within 
a module

See the test case I added (issue-2316-c) for a concrete example.
issue-2316 also contains the originally reported test case. resolve
was using bitwise or instead of logical or when checking exports,
resulting in excessively eager evaluation. A one-line fix that took
six hours to isolate ;-)

2db4259b35 Stop inferring bot/static when types/regions are unconstrained. 
Also, some other changes that came up along the way:
- add a 'blk' region for the current block.
- detect unused type/region variables.

85fbfa25d7 Revert "Eliminate a copy in syntax::parse::new_parser_from_file" 
This reverts commit 2bb3b63ec4379b812aeceb690d78763ec55d3cbb.

(I was confused.)

2bb3b63ec4 Eliminate a copy in syntax::parse::new_parser_from_file 
Fixing a FIXME turned out to be pretty involved. I added an io function
that returns a unique boxed string (for the contents of a file) rather than
a string, and went from there. Also made the src field of codemap a unique
boxed string. This doesn't seem to make that much difference in amount of
allocation according to valgrind (disappointingly), but I also had to introduce
a copy somewhere else pending a new snapshot, so maybe that's it.

43751e45d9 rustc: Rename llalign_of_real to llalign_of_pref 
This alignment is the "preferred" alignment of a type, which is not
necessarily the alignment the compiler will use when packing the
type into structures - that is the "ABI" alignment (in LLVM terms).

On x86, 64-bit ints have 8-byte preferred alignment, but 4-byte
ABI alignment.

825fd1808e lots of work to make iface/impls parameterized by regions 
- paths can now take region parameters, replacing the dirty hack
  I was doing before of abusing vstores.  vstores are now a bit
  of a hack though.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)
